RANDOLPH T. WINDLE, OF NEW YORK, N. Y.

BUMP.

Application led September 30, 1919.

To all whom t may concern.'

Be it known that I, RANDOLPH T. WINDLE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Pumps, of which the following is a specification.

rlhis invention relates to an improvement for pumps.

Some of the objects of the invention are: to improve the construction of the pump disclosed in an application filed by me October 6, 1917, bearing Serial No. 195,078; to provide a simple and inexpensive pump by using a removable plug or cap of wood or fiber having correlated therewith an etlicient and eectual fitting which accommodates the plunger rod rendering the pump air tight and non-leakable; to provide a novel form of stuing-box which is particularly applicable and consequential of the use of a wooden plug closure for the pump; to equip the pump barrel with a plug through which the plunger rod is operable, which may be readily inserted in the end of the barrel or readil removed therefrom to afford access to the interior of the barrel, so that any matter accumulating therein, which would prevent the proper working operation of the valve, may be removed. With these and other objects in view, the invention resides in the particular provision and combination of parts more fully described in the following specification and illustrated in the accompanying drawings in which Figure 1 is a central vertical sectional view through the pump embodying my invention.

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Referring now to the drawing, it will be seen, that the pump is to include in its construction, a barrel 10 which is equipped at one end thereof with an ordinary flap valve ll, a plunger on a plunger rod 13 is arranged for reciprocation in the barrel 10 and a removable closure 14C for the end of the barrel, opposite to that in which is arranged the flap valve 11.

As an item of economy in the production of pumps especially intended for pumping bilge water out of the holds of vessels or the like, which pumps require removable plugs or caps to permit ready access to the interior of the barrel because of frequent accumulation of substances or obstructions Specification of Letters Patent.

Patented May 11, 1920.

Serial No. 327,609.

in the barrel and the assemblage of the plunger in the barrel, each pump is equipped with a headed wooden plug 15 of substantial frusto-conical shape and is arranged in the end of the barrel 10, the head engaging the walls of the barrel. rIhe plug 15 is provided with a central bore 16 having arranged therein a metallic liner 17 which receives therethrough, the plunger rod 13. The liner 17 is provided with screw threads at either end to receive a nut 18 at one end thereof which yengages the bottom face of the plug 15 and receives at the upper end thereof a stufIing-box 19 having the usual packing 20 and a gland 2l threaded onto the upper end of the liner 17. A box 22 has threaded engagement with the gland 21.

From the foregoing, it will' be manifest that a novel form of closure for the pump barrel is provided and that there is correlated with the plug, as a consequence of the use of an inexpensive non-metallic plug, a non-homogeneous stuffing-box, to properly accommodate the plunger rod rendering the pump air-tight and non-leakable.

What is claimed as new is 1. An improvement for a pump consisting of a removable non-metallic plug frictionally engageable with the wall of the barrel of the pump, a metallic liner extending through said plug adapted to receive the plunger rod and a stufling-box secured to one end of the liner adapted to surround said rod.

2. An improvement for a pump consisting of a removable non-metallic plug frictionally engageable with the pump barrel wall, a metallic liner extending through said plug having a nut at one end and a gland at its other end, a box secured to said gland and packing within said box.

3. An improvement for a pump consisting of a removable non-metallic plug frictionally engageable with .the pump barrel wall, a metallic liner extending through said plug, said liner being screw threaded at either end, a nut threaded to one end of said liner, a gland threaded to the other end of said liner, the nut and the gland serving to hold the liner positioned in the plug, a box secured to said gland and packing within said box.

In testimony whereof I have axed my signature.

RANDOLPH T. WINDLE.
